On a rainy night three years ago, an explosion claimed the lives of his comrades, and the masked "ghost" principal culprit was at large. Lin Yan has since become the cold-blooded and ascetic captain of the police force.
Three years later, Su Wan, a sassy policewoman, parachuted in to form a team, and the first case was a jewelry store robbery - the suspect was armed with a bomb, and his modus operandi was exactly the same as that of the "ghost gang"! During the street fight in the rain, Su Wan jumped up to block the explosion for him without hesitation. Her words "Captain Lin, I will protect you this time" instantly broke his long-frozen heart.
The flaw in the wolf fang pendant in the interrogation room, the dark warning reported anonymously, the old accounts that were not settled three years ago... The conspiracies are intertwined, and the murderers are closing in step by step. They are partners in solving crimes with great tacit understanding, and they are also soul mates who guard each other. While tracing the source of the murder, they are spreading sugar in the hail of bullets to heat up the situation.
With the police badge as an oath and love as a shield, the two criminal police forces will join forces to finally reveal the true face of the "ghost", nail the evil on the justice bench, and protect each other every day and night for the rest of their lives!
